The problem is this was > ignored for HSHA previously, so some people go through this scenario: > 1. start with sync and 4000 threads > 2. switch to HSHA, pre-7594 > 3. upgrade to a version after 7594, without changing this setting > 4. experience awful performance due to insane thread contention -- This message was sent by Atlassian JIRA (v6.3.4#6332)
